While I'm no expert on these, the detail on the airplane is very weak.

And the catch is wrong on the back side.

This particular style of Bavarian pilot badge has been discussed recently on the WAF forum (in the last 2-3 weeks), and the catch has been pointed out as being incorrect in the way they tried to make it.

This particular style with a "Poellath" marked case has literally been flooding the market on eBay USA over the past year or more from a seller in Germany who has an endless supply of them, along with Pour le Merite, Tank Badges, Sub Badges, etcetera. He lists and sells them week after week, for over a year's time.

I honestly don't know if the buyers of the garbage from this eBay seller from Germany think they are getting a "bargain" on something they hope is real, or if they know their badge is bad and they simply want an expensive "filler" for their collection. I don't know what the mindset is of the endless supply of customers for this seller on eBay USA. And he has No negative feedback which is amazing.

If you seriously want to collect these Imperial Flight Badges, you need to "Pony Up" and buy the 2-volume set by Stephen Previtera (Imperial Sky, Vol 1 & 2), the Carsten Baldes book, and the Robert Pandis books (which I do not have yet).

I like the Pandis books. Especially sence I'm listed in the photo credits

No, Quite to the Contrary. It would be very odd if any hollow back or "cliche" stamped open backside Pilot badge that looks like this would have any hallmark on it whatsoever. Only the hollow ones that have the plate over the back are the type that were hallmarked. And then not all of those type were hallmarked.
